scripts_regression_tests.py failing with Error: Type mismatch between actual argument at (1) and actual argument at (2) (INTEGER(4)/LOGICAL(4)).

[AshaJain]

Hello!
I am new to CIME and CESM and am trying to port CIME/CESM to my Mac (running macOS 12.1). I am running into issues during the setup process with `scripts_regression_tests.py` failing with `Error: Type mismatch between actual argument at (1) and actual argument at (2) (INTEGER(4)/LOGICAL(4)).` and similar errors across 18 different tests. This is preventing me from running the consistency tests and moving forward.
Attached are the main files I use.
The compilers installed on my machine are GCC 11.2.0_3.
I am using `-fallow-mismatch-arguments` flag in the `FCFLAGS` and `FFLAGS` environment variables. These variables are set in the bash environment and in the environment variables section of config_machine.xml for the `homebrew` machine. However, this did not appear to work. I also noticed that the tests are using mipf90 to compile even though I specified gnu in the machine config XML file (see an example in test_errors.txt). Could this explain why the tests are failing? If so, why is GNU as specified in the config_machines.xml not being picked up and how can I ensure that GNU is being used to compile these files?

Thank you in advance!
AJ

Please try cesm2.1 (release) or cesm2.3 (development) cesm2.2 is an orphan and I don't recommend it. As far as mpif90 - if you do
mpif90 --version you should find that it is your gnu compiler.

Hello, I checked-out and pulled cesm2.1.0. However, I am still running into the same problem. Any other ideas as to what I could be doing wrong?

There were major changes in the gnu compiler after version 9 that haven't been backported to the cesm2.1 release.
Either try 2.3 or use an older gnu compiler version. (gnu/9.4.0 should work)
